Sorry if my reviews seem to be obnoxious, but I noticed an oddness you
surely can explain:
Chips with the old erase function spi_chip_erase_60_c7 seem to be
missing the c7 variant after conversion. And I think some of the chips
supports both 52 and d8 for block erase with same sector size and only
one is listed.
We have to list all known erase function variants even if they have
identical eraseblock sizes because on Intel/VIA chipsets one (or more)
of the commands may be forbidden by the chipset configuration.

I'm impressed by the amount of datasheet reading you did in such short
time. Keep up the good work!
